Yes. Ballast water is Transport Canada's domain, not DFO's. We provide the science to support it. That said, yesterday some of my staff were providing presentations on ballast water exchange in the Arctic at a conference related to invasives across the international scope, and there was a lot of interest in the Arctic.
If we do mid-ocean and we do the Canadian standards for ballast water exchange, we're thinking that we're in pretty good shape. I think what we have to look at, particularly in the east as we're coming in—and it would be the same thing in the Beaufort because of the shallow waters in the near shore—you'd want to make sure that you weren't bringing in something that could survive.
As an example, the Mary River project, when it's up and running, is going to be taking a lot of iron ore between the Mary River facilities and Rotterdam. Rotterdam is known for being one of the highest invasive breeding grounds in the world, I guess, because of the shipping traffic. What we'd be looking for is making sure there was some kind of mid-ocean exchange, and then, as it got closer to the destination, potential treatment or whatever under the regulations that Transport would put in place. The science we have sort of says yes, that should be sufficient.
